ANTISEPTIC THERMMETER-CASE.

SPECIFICATION forming part of kLetters Patent No. 752,395, dated February 16, 1904.

Application tiled October 13, 1902.

To ali whont it may concern.'

Be it known that I, PHTLIP C. HAY, a citizen of the United States, residing at Chicago, in the coun'ty of Cook and State of Illinois, have invented certain new and useful Improvements in Antiseptic Thermometer-Cases; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others 'skilled in the art to which it appertains to make and use the same.

'My invention relates to a novel antiseptic thermometer-case `for physicians, the object being to provide a device of this character in which the surface of the thermometer is constantly subjected to the action of an antiseptic luid and which will retain the fluid even though it be inverted, when the thermometer is removed without leakage; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

The accompanying drawing, illustrating my invention, shows my thermometer-case in cen- Referring now to said drawing, A indicates a cylindricalvessel, preferably of glass, having a neck portion B, to which a metallic neck is suitably secured, said neck being internally screw-threaded to receive the cap D, in which the thermometer E is mounted. Interiorly from the neck to about the middle of the body of the neck A extends a tube F, which is concentric with the body and between which and said body is anannular space G, the cubic capacity of which practically determines the amount of liquid whichthe vessel A will hold without danger of spilling. As will be obvious, if the vessel A is inverted the liquid contained therein will iiow into said annular space G or if laid horizontally will How partly into said space and remain partly in the body portion below; but under no circumstances will it spill any of the liquid.

The natural shaking to which the holder is subjected will causey the liquid not only to moisten the lower end of the thermometer, but by reason of a very small annular space between the thermometer and the tube F it F is shown larger than it would be Serial No. 127,142. (No model.)

will be drawn up into said tube by capillary vattraction and moisten it throughout its entire length. This is of course very essential, as physicians generally prefer to have patients take almost the entire length of the thermometer in the mouth. The splashing of the liquid in the tube tends to preserve the supply of liquid drawn up into the tube F by capillary action, and hence there is no need of having the liquid constantly on a level with the lower end of the tube, which also serves to do away with the chance of any spilling of the liquid. For the sake'of illustration the space between the thermometer and the tube made in practice.

I claim as my invention- 1. A thermometer-holder of the character described comprising an elongated cylindrical vessel having a contracted neck portion, a metallic neck portion internally screw-threaded and adapted to receive a cap, a tube concentricv with respect to the body of said cylindrical vessel and extending from the neck to the middle of the body forming an annular space betweenv the body and said tube whereby the liquid is prevented from escaping, substantially as described.

2. In ia device of the character described,

4the combination with an elongated cylindrical threaded surrounding said contracted neck portion, anda cap provided with a thermometer-receiving recess at the lower end thereof and adapted to be removably secured in the threads of the second neck portion, substantially as described.

In testimony whereof I aiiix my signature in presence of two witnesses.
